Sengoku Armors

In 1590, amid Japan’s turbulent Sengoku era, Izumi is the sole survivor of her village’s destruction and possesses a set of powerful keys. They can grant their wielder access to weapons capable of changing the course of the era. Fleeing those who want to kill her and seize the keys, Izumi washes up at a Buddhist monastery, where she meets the monk Tenkai. He takes an interest in her troubles, but may be more than he appears.
